F16 VIper and F18 C2 Shroud anchor upgrade. If you have a Viper and have not had your Shroud anchors upgraded and are coming to the Nationals in Sarasota, please contact Jill at 727-734-0799 or [email protected] We are going to try and replace these at the F16 Nationals in Sarasota in October. Replacement days will be Oct 16 & 17 for the C2.s and the 27th & 28th for the Vipers. You must be on the list to do it then.

What's the failure mode? I'm the 2nd owner, so not sure if my '10 C2 was ever done. Anchors are rock solid, but...

They snap off inside the hull. Check with Jill or Goodall Design when they stopped shipping boats that had the issue. You'll be able to tell if yours have been fixed post delivery because there will be a 1 inch scar in the gelcoat around the chain plate.

PM me your email address and I'll send you Jim Boyer's guide on how to effect the repair.

I had heard of some kind of campaign to replace these, but have to admit I hadn't taken it very seriously. Not liking the idea of a sudden failure. Not sure when or if I'll have my boat in Florida this winter. Will send a pm.

Edited highlights or the repair:

then...

Finally..

Is that tang just a bent piece of stainless with a nut holding it on the threaded bit? Would have liked to see the new tang before it was installed.

No the tang is a machined lug with a drilled and tapped thread that screws down onto the thread shown in the third last image. I believe from Rehmbo that this detail might have changed as he describes his as more like an eye bolt.

Scarecrow, that is the old capricorn tangs, the C2 / Viper uses and eye bolt. this has nothing to do with that repair nor are there any forecast failures.

So what is the upgrade Jill and Robbie are offering to do?

changing metric eye bolts for imperial ones.. or so i have heard...

That is not correct. The eye bolts have been known to fail and are being swapped out for larger ones. The new ones may be imperial but that has nothing to do with the issue.

Jeff, I doubt your boat was been swapped out, email Jill and ask her to send you the hardware and the instructions I'm sure it's not that difficult.

That is pretty incredible dealer support...I have to say.

In my case its not their fault. I'm about 1200 miles from them and haven't had my boat in FL in a couple years (something I need to rectify this year!)

100% agree! To be honest it's the only reason I'm on a C2 instead of an Infusion.

I noticed a rust stain on the first few pictures showing the damage.

Wonder if that stain's appearance indicated some sort of crevice corrosion prior to the ultimate failure?

Yep! Steeplechase, Tradewinds and Charlotte Harbour is a great winter series. Plus there is that week long event in October :-)

Infusion support has been fixed-Nacra NA is under new management. Our Mk. 2 is very well built and very quick.

My first though, as well. Good work.
